Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
530 AM AST Tue Apr 25 2017

.DISCUSSION...Shower activity will increase today across the
forecast area. Specially over the interior and northern slopes of
PR. Isolated thunderstorms are expected today. A moist
southeasterly wind flow will maintain RH`s above critical levels
today. A surface high pressure across the Central Atlantic will
promote moderate trade winds across the islands for the rest of
the week. A few showers can reach from time to time the east and
southeastern coastal areas of PR through Saturday...winds become
more east to northeast late in the weekend. At the moment, the
overall fire danger is expected to remain low.
